"When people ask if I'm going to be sad that The Office is over, they don't even understand the depth of that question for me," Krasinski told the Los Angeles Times.

"It's an era of my life. No one would have known my name if it wasn't for the show. I wouldn't have the opportunity to do any of the things I've done in my life."

However, the 33-year-old added that he is "trying to see" his post-Office future as an "exciting" time.

"Everyone's asking, 'What's going to happen to you?' - which I think sounds a little menacing," he admitted. "To jump now into total darkness and not have any way to get back will be really, really terrifying. But I'm trying to see it as exciting."
